To all whom it may concern.'

Be it known that I, JOSEPH Lnnnnnn, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Inverted Gas-Burners, of which the following is a specification.

rl`his invention relates to inverted gasburners of the Bunsen typo and has for its object the obtaining, in such a burner, of a superior mixture of gas and air to supply the Bunsen flame, of a superior, inv rted, unsen flame of high intensity, and other advantages hereinafter described and pointed out in the claims.

The invention is illustrated in the accompanying drawings which form part of this specication.

Figure 1 is an elevation, partly in vertical section, of an inverted gas-burner made in accordance with this invention. Fig. 2 is an elevation of the inverted gas-burner shown in Fig. 1, with the globe, inverted mantle and gas-supply pipe removed. Fig. 3 is a plan view from the top of the inverted gas-burner Shown in Fig. 2, with the section above the line e l) in Fig. 2, and the part below the globe holder, removed. Fig. d is an elevation, mostly in vertical section, of the gascheclr at the top of Fig. 2. Fig. 5 is a plan view from above of a horizontal section, except as to the plug l), of the gas-check shown 1n Fig. 11, made as indicated by the line a y. The arrows shown in Figs. 2 and 4 indicate, respectively, the directions of the views shown in Figs. 3 and 5.

In the drawings like letters indicate like parts.

A is a gas-supply pipe, shown in Fig. 1 in the shape of a goose-neck, but which may, however, be straight as well as curved or of any other suitable and convenient form or shape.

B is a gas-check for the regulation of the supply of gas to the inverted, Bunsen gasburner. The gas-check B may be of any suitable construction and it is, in any suitable manner, as by screw-threads, connected or joined with the gas-supply pipe A above and the burner-tube or pipe C below.

O is the burner-tube or pipe of the inverted gas-burner. The pipe C is suitably connect ed or joined, as by screw-threads, with the gas-check B above and the expansion chamber D below, and is provided, preferably at its upper part, with perforations or air-inlet holes E.

-D is an expansion chamber from which a pipe or tube F leads downwardly to the mouth or outlet G of the inverted gas-burner.

HH are projections or other suitable device, secured to the pipe or tube F, for attachment of the mantle support l provided with extensions KK suitable for engagement with the parts HH, from which support l the the inverted mantle J is suspended.

T he burner-tube or pipe C, the expansion A chamber l) and the pipe or tube F constitute a channel for the passage of the gas and air mixture to the mouth of the inverted gasburner, and it is not necessary, for the purposes of this invention, that the said channel be composed of several parts or that it be of any special form or shape; nor is the expansion chamber D a necessary part ofthe channel.

Surrounding the channel for the downward passage of the and air mixture to the mouth G of the inverted gas-burner is a chamber L which may be of any suitable form, preferably of the form of a cylinder provided with a dome-shaped top perforated to permit the gas-check B or channel for the downward passage of the gas and air mixture to enter the chamber L. Any suitable means may be employed for closing the chamber L at the top and for this purpose the rim M about the perforation in the dome-shaped top of the chamber L may be secured and pressed between the top of the pipe or tube C and an opposed projecting edge of the gascheck B, as shown in Fig. 1. The chamber L is provided, preferably at its lower part, with perforations N. rllhe chamber L should be so situated that it surrounds the perforations or air-inlet holes E in the channel for the downward passage of the gas and air mixture to the mouth G of the inverted gas-burner. The lower end of the chamber L rests upon and is closed by a suitable base O, which is, preferably, a slightly convex piece of metal surrounding the channel for the downward passage of the gas and air mixture. The base-piece O may be sup sorted in any suitable manner, as by a nut screwed upon the outer surface of the channel for the downward passage of the gas and air mixture which may be provided on its interior surface with screw-threads for such purpose. The base-piece O extends outwardly and, preferably, to the globe-holder R which it may support and with which it may be made in one piece. The base-piece O is provided on one side with one or more perforations S and is otherwise closed. The parts of the basepiece O on the inner sides of the perforations S are, preferably, bent upwardly at an angle forming defiectors T. rihe base-piece O is referred to as a shield in the claims.

The chamber L and the base-piece O are so adjusted, one to the other, that the perforations N of the chamber L are situated above and near the closed part of the base-piece O and the closed part of the chamber L is situated above and near the perforations S and the deflectors T of the base-piece O. 1n order to facilitate the described adjustment between the base-piece O and the chamber L, the chamber L should, preferably, be provided with notches U at its bottom, and the base-piece O with ridges or elevations V, the notches U and the ridges or elevations V being so shaped that the ridges or elevations fit closely into the notches. By means of the nut Q the base-piece O maybe pressed tightly against the bottom of the chamber L and the proper adjustment between the two may thereby be maintained. A Olobe vW may be suspended from the globe-ho7`lder il.

From the foregoing description of the different parts of an inverted gas-burner, made in accordance with this invention, the function and mode of operation of the burner will readily be understood. Gas enters the gassupply pipe A and the flow of gas may be regulated, if desired, by the gas-check B. Upon reaching the air inlet holes E in the channel for the downward passage to the mouth G of the burner, the gas becomes mixed with the air entering through the holes E and a mingling or mixing of the gas and air continues until the gas and air mixture issues from the mouth of the burner where it supplies the inverted Bunsen flame which heats the inverted mantle J to incandescence.

The products of combustion, the result of the flame burning at the mouth G of the burner, rise in a heated condition and pass or escape through the perforation S in the basepiece O and are deflected from the chamber by the deflectors T. The products of combustion do not, therefore, enter the chamber L through the erforations N. Pure air, the oxygen of whic has not been exhausted, as is the oxygen of the air which has mingled with the gas to form the Bunsen flame burning at the mouth G of the burner, enters the chamber L through the perforations N and from the chamber L is drawn into the channel for the downward passage of the gas and air mixture through the perforations E. An efficient and proper supply of ure air, not exhausted of its oxygen, is, t erefore, secured in an inverted gaseburner made in accord-ance with this invention. Moreover, the parts above the inverted Bunsen fiame become heated, including the chamber L, and by reason of the heated condition of the chamber L and its surrounding parts, the suction of air into the chamber L through the perforations N and into the channel for the downward passage of the gas and air mixture through the air-inlet holes E is considerably increased. Furthermore, the air in passing through the heated chamber L becomes heated before entering the air-inlet holes E and mixing with the gas. The result is that in an inverted gas-burner, made inV accordance with this invention, a superior mixture of gas and air for the supply of the inverted Bunsen flame is obtained, because, among other reasons, the air employed for forming the gas and air mixture is pure air not exhausted of its oxygen, and is heated air, and is air which, because of its heated condition, enters the chamber L and the airinlet holes E at a higher rate of speed. Such a mixture of gas and air, containing a proper supply of oxygen, issues with greater force or speed at the mouth G of the inverted burner and produces, in burning, a Bunsen flame of superior size and shape and of exceptionally high intensity, ca able of raising the inverted mantle to a high c egree of incandescence.

Another advantage secured in an inverted burner made in accordance with this invene tion is the protection which is afforded to the gas-supply pipe A by the closed portion of the base-piece O. 1n cases where the gassupply pipe extends laterally, as does a goose-neck, the burner and the gas-supply pipe may be so adjusted that the gas-supply pipe will be situated above the closed. portion of the base-piece O and thus be protected against over heating by the rising, heated products ofcombustion.

A further advantage secured in an inverted burner, made in accordance with this invention, is the absence of any lconsiderable amount of friction in the passage ofthe gas and air mixture from the air-inlet holes to the mouth of the burner, sincethe channel is, preferably, short and straight and the friction which is encountered by the gas and air mixture in an inverted gas-burner provided, for example, with a long goose-neck tube having the air-inlet holes at the farther or lower end of the gooseneck is avoided.

It will be understood by those skilled in the art to Which this invention appertains that variations may be made in details without departing from this invention.
